But the lug or enlargement outside of the wheel is here soarranged that ,the cutterV cavity is radial to the wheel, as shown in 1 Fig. 89. The cutter H is similar in shape to those at but itsstem lies in .ahorizontal position, that is, in a piosition parallel to e wheel.

At I-I there are ropes, and at 1-13 ropewinding drums each havingfone end of one of the ropes' attached thereto. The other end of the rope'is adapted to be Inadefast .Y tosouie post, anchor or stationary object toward which the machinev can be drawn. The winding' drums are secured tothe shafts z' which at their inner ends are mounted in bearings i carried by thel bearing frames or blocks I4 (F ig. 37) which are secured to the downward projections or bosses a2 on the :frame A, these bosses or projections cl2 being thereof.

Z is a shaft mounted at its inner end in a bearlng l in the block or frame 1* and near lts outer end 1n the bearing L which 1s secured to the frame A.

M is a gear wheel rigidly secured to the shaft Z-Z and is adapted t0 mesh with the gear wheel M2 rigidly secured to the drum shaft z'. M is a ratchet wheelrigidly secured'tov thevshaft Z.

L is a radius arm or pawl carrier mounted on the shaft Land N is the pawl carried thereby' and, adapted to engage with the ratchet teeth 'on the wheel M.

This pawl is preferably yieldingly held in engagement with the ratchet teeth by means of a spring 'n' which is. preferably made in the shape of a loop as show-n. yn is a 'lateral projection or lug on the -frame A ring loops n is adapted to engage. nis a aterall rojectin handle ont e'said awli It wi 1 e seen t at when it is desire` to have this locking pawl in operation that it is merelyne'cessary to press downward on the handlejn andffcrce the spring A under side of the lugor proJection Wes shown in `Fig-"2. When the disengagement" of thepawll is. desired ther ringn b e pressed to the upper side of tie projection I or lug n andthe pawl will be held out of engagement. At.. the other end of the machine there is 4a similar set of parts connected to the winding drum If. The radius arm4 L of this set of parts can be connected to the eccentric strapby means of the pitman K,the latter. being ladapted to be disengaged from thestrap and again connected up with Ieither set of rope-winding devices.. In order to regulate the speed of travel of t the machine I provide for each ratchet and pawl mechanism a sliding plate K (Fig.

30) which-'is seated in 'an aperture r7c in the bearing frame I5 and which is project through said frame and extend over the teeth of the ratchet wheel M.

'(Fi s. 15 andl); This is mounted, at'p Vin tie mainframeorfin a supplemen'talj Iframe piece"v P (Figs. v19 and' 20') secured "to the .mam

At g there is nn enlargement or heed on the adjusting bolt Q, this bein@ preferably convex and sented in cavity s* in the end of the frame piece P. The concave cavity in which the head. of' the adjusting; bolt is seated is preferably formed in s bushing p5 (Fig. 18) which is litted into an eperture in the freine piece. By applying n wrench to the end of the adjusting bolt, it can be turned in such e Way :is to swing the Wheel carrier and raise and lower the end of the machine relative to the Wheel. By these devices the mechanism can be tilted. one end relatively to the other, so as 'te vary in horizontal, the line of the cnt made by the cutter Wheel. As the exposed ends or heads of the adjusting bolts Q :1re situated at the ends of the machine, and since the bolts are substantially horizontally disposed, they Lire easily accessible for iidjustment. The wheels and their carriers ere arranged below the cylinders E, which e2;-

tend beyond the platform-like parts c of the bed freine, this arrangement reducing` the length of the niechine and bringing;- ie Wheels Well under the they e.; to suie port, Whiie at the sinne time les ing es posed end in easily accessible positions the parts by which the vertical adjustments o3? the. .traine ere etfected.

The cutter Wheel, it will be seen, is nonn'i ed midway between the ends of the .dici as a Whole, and is adapted for use when machine is moving in either direction, being merely necessary to reverse the ters to correspond to the line olf ndvz .l e.

The reversal of the engines may be eccomplished in any well known manner. ln the drawings I have shown 'the valve stems lli, B. ci the engines connected to Yeccentrics S, S which are loosely mounted on the engine shafts B', B. rThe eccentric disks T, T (Fig. 26) ere keyed 'to the said engine shafts, each eccentric dish having e concentric slot t throng-gli which the bolt which clamps the eccentric to its tends. in oi'lr to i. disk e reverse the enginestheir eccent shifted across the face to theii c. ti' i. disks and clamped in the reversed pditnin.v ,Tor itinere detailed description cit' the nicchanisin herein indicated, for reversing' the engine, reference may be made to Patent No. '878,96, issued February il. 1908, to F. R. ll'lerrill for ininingrnztcliines.

By arranging the j'v in fili shown inthe drasfi n, releti J and low machine cielly desirable for use in long .-v'zill Work. The present construction also permits of the operation oi the machine in either direction, and the engines are in nlinernen't with ench'otnei and on opposite sides oi the crank .shaft and have their cranks 90 deto each other. the vibrationv of one vili be .more or less compensated for by the vibrations of other.

.of the relatively long as has formerly been done, not only is itpos vsible to adjust the bits on cuta wider kerf, but also the wheel may be more quickly and readily detached from the frame. Furthermore -since Athrust on the wheel is normally downwardly, the danger of stripping the threads of the bolts which support the quadrant plate, incident to the construction in which the quadrant platebears downward on the bolt heads, is avoided by applicants construction, andr the machine may be worked closer to the coal.
